I will stop picking!

I've been picking at my skin for just over 2 years now and I can honestly say it has ruined my life. I am a 20 year old girl who has no job (I quit due to my face picking and the embarrassment it was causing me - I worked as a sales assistant in a busy shopping centre). I also have no social life and have literally only left my house about 5 times in the past 3 months. I am a total wreck over this condition and today I have decided enough is enough and I WILL sort my life out! I mostly pick at my face and have so many scars left over from my self destructive behaviour... I just hope in time they fade. I also pick at my chest/ shoulders and back but not in the extreme way I pick my face. I never sufferered with spots throughout my teenage years, it was only when I turned 18 after leaving college and with the stress of looking for a job I started to get spots on my face. I am obsessed with getting the gunk out of my spots and feeling around on my face for any small bumps or imperfections I can find! Basically I can't take this anymore and need to stop, so if anyone has any advice or helpful tips to help me stop picking it would be very much appreciated! I am trying to remain positive and keep telling myself I CAN do this and stop picking for good :-) fingers crossed!
